Answer:
An airline claims that the no-show rate for passengers is less than 5%. In a sample of 420 randomly selected reservations, 19 were no-shows. At α=0.01, test the airline's claim. State the sample percentage and round it to three decimal places.
State the hypotheses.
State the critical value(s).
State the test statistics.
State the decision
State the conclusion.
First find the equation of y.
Find the slope m.
.
Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.
.
The equation of a line y is:
.
The perpendicular line 
is same like the normal line except its slope m becomes:
.
The equation of a perpendicular bisector is thus:
.
Hope this helps.
to inverse a equation make all y's x and andy x's y
Thus the inverse is
x=4y-8
Evaluated to
4y=x+8
y=
Answer:
Approximately 2 weeks
Step-by-step explanation:
Given data
Cost of bike= £250
<em>Assuming she works for 6 days</em>
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her
=250/126.5
=1.97 week
Approximately 2 weeks to save up the amount
